History of Julius Caesar Vol. 2 of 2

The combats of cavalry took place in the plain which extends from the small eminence called Le Puy-de-Marmant to the marsh of Sarlièves.

The hill is certainly the Roche-Blanche, for it is situated opposite the oppidum (e regione oppidi); it begins at the very foot of the slopes of the mountain of Gergovia (sub ipsis radicibus montis), is singularly fortified by nature, and, as it were, cut out from all sides (egregie munitus atque ex omni parte circumcisus). So long as the Gauls occupied it, they could go to the Auzon by the ravine of Merdogne, to obtain water and forage; but as soon as it was in the power of the Romans, the Gauls were compelled to draw their water from the springs on the mountain of Gergovia, and from the little brook of Artières.

The excavations made in 1862 brought the two camps to light. The fosses of the little camp are clearly defined in the calcareous soil. They form an irregular outline, represented on Plate 22. The Roche-Blanche, which presents in its southern part an escarpment almost as perpendicular as a wall, has lost on the sides its abrupt form by successive landslips, the last of which took place within memory of the inhabitants. The communication between the great and little camps was composed of a parapet, formed by the earth thrown out of two contiguous fosses, each four feet in depth and six in breadth, so that the breadth of the two together is only twelve feet. If we wonder that the Romans should have dug two little ditches, each six feet broad and four feet deep, instead of making one eight feet wide by six feet deep, which would have given the same amount of soil to take out, it may be answered that the two little ditches were much more quickly made than one large ditch.

Plate 22 shows the places which Cæsar’s eye could embrace from the summit of the Roche-Blanche. He could see neither the plateau, nor the country situated on the norther slopes of the mountains of Gergovia and Rissoles. It was for this reason that he had to learn from the deserters the form of the ground which lay on the other side. He thus learnt that the ridge of this latter mountain (dorsum ejus jugi) was not very uneven, and gave access to the western part of the town (ad alteram partem oppidi) by a narrow wooded passage (the defile of the Goules, which separates Rissoles from Gergovia). (See Plate 21 in C.) This defile leads to the gate P of the oppidum. The foundations, of masonry, and the approaches to this gate, were uncovered in the month of July, 1861. The wide road which led from this gate to the defile C is distinctly seen. The alarm of Vercingetorix may be imagined; he feared lest the Romans might shut up from the Gauls this issue from the oppidum. These latter would have been almost blockaded (pœne circumvallati), without any way out, and in the impossibility of producing forage from the valley of the Artières, since the northern part of the town was difficult to access. Consequently, the words si alterum collem amisissent can only apply to the mountain mass of Rissoles, and not, as several authors have pretended, to Montrognon or to Puy-Giroux; for the possession of those two peaks, detached and rather far from the mountain mass of Gergovia, offered no interest either for the attack or for the defence.

The spot which it was important for the Gauls to fortify was the part D E of the heights of Rissoles which are opposite the village of Opme, because troops could only scale the mass by the western slope. How can any one suppose that, fearing for the defile of the Goules, the Gauls would have abandoned their camp before the place to go and entrench themselves on Montrognon, three kilomètres from Gergovia? How admit that Cæsar, to threaten the defile, would have sent troops to make the circuit of the mountain of Gergovia by the north? How could the legion, which supported this movement, without advancing far, and which concealed itself in the woods, have assisted in the stratagem, if the false attack had been made to the east and to the north of Gergovia, at two leagues from the camp? In passing by the south, that is, by the defile of Opme, the legion was always in communication with the camps, on which it could fall back, and the broken and wooded ground prevented the Gauls from knowing accurately the importance of the attack. Besides, two facts which result from the “Commentaries” prove that the Gauls were not very far from the oppidum. Cæsar sees the southern front abandoned, and he establishes his legions at a distance of 1,200 paces from the place. The soldiers scale the heights at a rapid pace; but scarcely have they reached the principal enclosure, when the Gauls, who hear the cries of the women and of the small number of defenders left in the place (primo exaudito clamore), have time to hurry to them, and drive back the Romans. Consequently, the Gauls were at a distance where the cries could be heard; and this distance may be measured by the time which the attacking columns must have taken to climb the space of 1,200 paces, since they arrived almost simultaneously. We believe, therefore, that they were at a distance of less than two kilomètres from the gate O of the town, engaged in fortifying the plateau of the heights of Risolles.

492

According to Polyænus (VIII. xxiii. 9), the soldiers marched with their heads bent down, in order not to be seen.

493

It is, in fact, 1780 mètres from the foot of the mountain, where Cæsar must have assembled his troops, between the Roche-Blanche and the Puy-de-Marmant, to the gate O of the oppidum. This is the line which passes by the ravine in which the village of Merdogne is situated; to the left and to the right the ground is too rugged for the troops to climb it.

494

General Gœler believes, with apparent reason, that we ought to read regressus instead of progressus. The 10th legion, which acted as reserve, must, in the presence of a combat, the issue of which was uncertain, have taken up a position behind rather than towards the front.

495

The part of the southern slope of Gergovia which was the scene of the last battle is clearly indicated by the ground itself. This battle took place on the whole space which extends in front of the gate O of the oppidum, the principal object of the attack. The ravine which, according to the “Commentaries,” prevented the legions from hearing the signal to retreat, is that which descends to the west of the Merdogne. Hence it may be concluded that, at this moment, Cæsar and the 10th legion were to the right of this ravine. Lastly, we understand on the spot the movement of the Ædui. To the east of Merdogne there is a spur, H, attached to the mountain of Gergovia, forty mètres below the table-land, and presenting several successive terraces. So long as the Ædui, who came from the east, had not arrived on the crest of this spur, they could not be perceived by the Romans, who were fighting towards Merdogne; but it may be imagined that, when they appeared all at once on this crest, and at a distance of 600 mètres from the right flank of the legions, the sight of them must have singularly surprised the troops, who were expecting no re-enforcement from that side.

General de Gœler, without having seen the locality, has indicated nearly the site of the Roman camp; but he does not place it sufficiently to the west. He makes the Gaulish troops encamp on the four slopes of the mountain of Gergovia. It is, no doubt, the expression circum se (VII. 36) which led him into this error. It is, indeed, impossible to admit that the Gauls could have encamped on the abrupt slopes of the northern declivity. General de Gœler is also mistaken in directing the false attack upon Montrognon. Lastly, he places the scene of the battle too much towards the west.

“In the war of the Gauls, Caius Julius Cæsar was surprised by an enemy, who carried him off, armed as he was, on his horse, when another Gaul, who recognized Cæsar, called out, intending to insult him, “Cæcos, Cæsar!” which in the Gaulish language signifies, let him go, set him loose; and so he escaped. Cæsar says so himself, in his Ephemerides, in the passage where he speaks of his good fortune.” (Servius Maurus Honoratus, a grammarian of the fifth century, in his commentary on the 11th book of the Æneid, line 743, II. p. 48, edit. Albert Lion.)

The manuscripts of Servius do not all present the same reading. The following are some of the principal variations: Cecos, Cæsar; Cæcos ac Cæsar; and Cæsar, Cesar.

A sling-ball of lead has been found at Sens, on which are stamped in relief the words “T. Labienus.” This ball forms part of the collection of the Museum of Saint-Germain.

502

MM. de Saulcy and J. Quicherat have already demonstrated in a conclusive manner that Labienus must have followed the left bank of the Yonne, after leaving Sens, and that he crossed over to the right bank of the Seine at Melun. In fact, Labienus, on the right bank, found himself, as Cæsar says, threatened on one side by the Bellovaci, on the other by the army of Camulogenus (VII. 59). On the opposite bank, on the contrary, Labienus would not have been placed between the two, since he would have had Camulogenus in front, and, at a greater distance, the Bellovaci coming from the north.

“A very large river kept the legions separated from their reserve and their baggage.” This very great river cannot be the Marne, which Cæsar does not even mention in the whole course of this campaign: it was evidently the Seine, which Labienus has crossed once only, at Melodunum (Melun); by crossing over to the right bank, he was separated from his base of operations, which was at Sens. On the contrary hypothesis, no river would have separated Labienus from his line of retreat; unless we admit, with Dulaure and several others, the identity of Agedincum with Provius, which is no longer possible.

The Captain of the Staff Rouby has made investigations on the spot, which prove that from Sens the most ancient ways leading to Paris passed on the left bank of the Yonne and of the Seine. Moreover, the discoveries of M. Carré have made us acquainted with the exact direction followed by the Roman road after quitting Sens towards Paris; it was entirely on the left bank of the Yonne. If Cæsar’s lieutenant had followed the right bank of the Yonne, he would, the day after his departure, have been arrested by the course of the Seine, and would have fallen in with the Gaulish town of Condate, built in the very angle of the two streams, in the midst of perhaps impassable marshes. If only a few thousand Gauls had occupied the heights which played so important a part in the campaign of 1814, Labienus, compelled to seek for a place to cross higher up the stream, would have been diverted considerably from his aim.

It has been supposed wrongly that the Bièvre was the marsh where Labienus, in his march on the left bank of the Seine, had been arrested by the Gaulish army. Leaving out of consideration the fact that the Bièvre, which flows through a calcareous soil, can at no epoch have formed a marsh capable of arresting an army, how can we suppose that Labienus, if he had arrived at this stream, that is, close to Lutetia, would have retraced his steps as far back as Melun, to march from thence towards the oppidum of the Parisii by the right bank of the Seine, which would have obliged him to make a journey of twenty-four leagues? The manœuvre of Labienus can only be explained by his desire to turn the strong position of Camulogenus, and arrive at Paris before him. The text of the “Commentaries” says clearly that Labienus, stopped by the marsh which shelves towards the Seine, stole away by night, surprised the passage of the Seine at Melun, and marched upon Lutetia, where he arrived before Camulogenus. To allow of the success of this manœuvre, the marsh in question must necessarily not have been far from Melun. The Essonne alone fulfils that condition. The ground on the banks of this little river offers, even at present, by its nature, a very serious obstacle to an army. It is cut up by innumerable peat mosses; and it was behind this line of Essonne that, in 1814, the Emperor Napoleon I. established his army, whilst the enemy occupied Paris.

503

We have not translated these words, fugam parare, because this passage has always appeared unintelligible to us. How, indeed, could the Gauls, seeing that the Romans were ready to pass the Seine by force, believe that this was a flight?

504

Some manuscripts have Metiosedum, a version which, in our opinion, is utterly incorrect.

508

Let us here recapitulate the numbers of the legions employed during the war in Gaul. Cæsar’s army, as we have seen, was composed in 696 of six legions, the 7th, 8th, 9th, 10th, 11th, and 12th. In 697, two new legions were raised in Italy, the 13th and 14th. Probably, in the winter between 699 and 700, Cæsar brought several cohorts composed of soldiers and sailors who were to serve in the fleet; for, on his return from the second expedition into England, notwithstanding the losses he had sustained, he was at the head of eight legions and five cohorts (V. 24). He lost at Aduatuca one legion and a half, that is, the 14th legion, besides five cohorts; but in 701 three new legions replaced the cohorts lost, and even doubled their number. These legions were the 1st, lent by Pompey (De Bello Gallico, VIII. 54, and Lucan, Pharsalia, VII., 1. 218); the 14th, which took the number of the legion destroyed at Aduatuca (De Bello Gallico, VI. 32; VIII. 4); and the 15th; this last legion was afterwards, with the 1st, given to Pompey for the war of the Parthians; it figured in the Civil War, and took, in Pompey’s army, the number 3. (Cæsar, De Bello Civili, III. 88.)

The 6th legion, judging from its number, must have been one of the oldest, for Dio Cassius (XXXVIII. 47) informs us that the legions were designated according to their order of inscription on the rolls of the army; but, as it only appears for the first time in 702, it is probable that it had remained in garrison among the Allobroges or in Italy. A proof that this legion assisted in the siege of Alesia is found in the fact that, after the surrender of the place, it was sent to winter quarters on the Saône, where Cæsar found it a few months afterwards (De Bello Gallico, VIII. 4). The distribution of the troops in their winter quarters after the taking of Alesia confirms the number of legions given above. The re-distribution after the siege of Uxellodunum gives also the same result, for in book VII. c. 46 the “Commentaries” give the positions of ten legions, without reckoning the 15th, which, according to book VIII. c. 24, had been sent to Cisalpine Gaul. These facts are repeated again, book VIII. c. 54.

509

It is evident that an army could not remain in the wars for eight years without receiving frequent re-enforcements in order to keep it up to its effective number. Thus, when, after the murder of Clodius, all the youth of Italy had been called to arms, Cæsar made new levies, which were used probably to swell the ranks of his legions, for no new numbers appear (De Bello Gallico, VII. 1). – In the same manner, when he arrived, in 702, in the south of Gaul, and crossed the Cévennes, he placed himself at the head of the troops which had been recruited in the Roman province and of the re-enforcements which he had brought from Italy (partem copiarum ex provincia supplementumque quod ex Italia adduxerat in Helvois, qui fines Arvernorum contingunt, convenire jubet). (De Bello Gallico, VII. 7.) – Labienus, on the other hand, during his expedition to Paris, left his recruits in dépôt at Sens (Labienus eo supplemento quod nuper ex Italia venerat relicto). (De Bello Gallico, VII. 57.)
